Choosing Technology

Behavioral Interview Guide

Interview Question: Tell me about a time you had to choose a technology or framework for a project.

Technology choices have long-lasting implications. Interviewers want to see that you don't just pick what's trendy—you evaluate options based on team skills, project requirements, scalability needs, and long-term maintainability.

What Interviewers Are Looking For

  • Requirements Analysis: Did you understand what the project actually needed?
  • Team Considerations: Did you factor in team expertise?
  • Long-term Thinking: Did you consider maintainability and scalability?
  • Risk Assessment: Did you evaluate maturity and community support?
  • Pragmatism: Did you avoid over-engineering?

✓ Strong Answer

"For our new microservice, I evaluated Go, Node.js, and Python. Go had best performance but team had no experience. Node.js fit our team skills and ecosystem. I built POCs in each, presented trade-offs to the team. We chose Node.js—shipped on time and onboarding new developers was easy."
